AP4-43

Revisión del cliente

Based on 1 Customer Validation

AP4-43 is an orally active CLK1, CLK4, PI3K, DDR1, EGFR and NEK4 inhibitor. AP4-43 reduces growth of mammalian colorectal cancer organoids. AP4-43 improves survival in a transgenic Drosophila model of KRAS-mutant colorectal cancer. AP4-43 can be used for the research of KRAS-mutant colorectal cancer.

In Vitro

AP4-43 (10 pM-100 μM; 72 hr) inhibits the viability of SW620 human KRAS-driven colorectal cancer cells with an IC₅₀ of 2.23 µM and SW837 cells with an IC₅₀ of 15.41 µM^[1].
AP4-43 (2 µM) reduces the growth of AKP mouse KRAS-mutant colorectal cancer organoids more effectively than 2 µM Regorafenib (HY-10331)^[1].
AP4-43 (2 µM; 24 hr) inhibits CLK1-dependent Wnt/β-catenin signalling and CLK4-dependent NF-κB activation in AKP mouse KRAS-mutant colorectal cancer organoids, without affecting PI3K-AKT or RAS-MAPK pathway activity^[1].

Cell Line:

SW620 and SW837 cell lines
Concentration:

10 pM; 100 pM; 1 nM; 10 nM; 100 nM; 1 μM; 10 μM; 100 μM
Incubation Time:

72 h
Result:

In Vivo

AP4-43 (1-100 µM; p.o.; continuous feeding in media) enhances survival of a patient-matched Drosophila colorectal cancer model by targeting a multi-kinase network including CLK1 and NEK4, with synergistic efficacy observed when combined with reduced NEK4 gene dosage, reaching 78.5% survival in this context^[1].

Animal Model:

Drosophila melanogaster (using byn-GAL4, UAS-GFP, GAL80ts and UAS-RAP-p1 transgenic lines; transgenic model expressing oncogenic Ras^G12V plus shRNAs targeting orthologues of human tumour suppressors Apc, P53, ago, wts, CG7742, and Atg2 in larval hindgut)^[1]
Dosage:

1 µM; 10 µM; 100 µM
Administration:

p.o.; continuous feeding in media
Result:

Significantly improved byn>RAP-p1 survival over parent compound AP2-83 across multiple concentrations.
Reached 16.83% survival in byn>RAP-p1 flies at 10 µM alone.
Increased byn>RAP-p1; nek4^-/+ fly survival to 78.5% (P < 0.0001) and caused significant reduction in hindgut proliferation zone area when combined with heterozygous loss of Drosophila NEK4 orthologue at 10 µM.
Improved survival in byn>RAP-p1; dyrk3^-/+ flies when combined with heterozygous loss of CLK1 orthologue at 10 µM.
Did not improve survival in byn>RAP-p1; ddr^-/+ flies at 10 µM.
Reduced survival in byn>RAP-p1; egfr^-/+ flies at 10 µM.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
